It looks like Google have introduced some bibliography software functionality to their Google Scholar. Now you can add Google Scholar results to your personal "library" of papers. And you can also assign labels (essentially - tags) to articles.

The interface for adding labels is slightly awkward (a bit too Gmail-style for my taste), but usable: to add a label to a paper you should first create a label (it will be empty just after you created it), then click on the paper title, get to the "paper page" (where the abstract is whoen), and there use a drop-down menu. A bit too many clicks to enjoy the process, but it's usable.
